AI Technical Summary

Technical Problem

Existing forestry seedling cultivation soil covering and compaction equipment lacks soil breaking function, resulting in uneven compaction, easy damage to seedlings, non-adjustable pressure, poor air permeability, low work efficiency, and inadequate cleaning device design.

Method used

It adopts a compacted soil breaking component and an independent elastic compaction component, combined with hydraulic push rods and spring adjustment to achieve precise adjustment of the breaking roller and adaptive compaction of the fan-shaped compaction plate. It is equipped with a cleaning device to prevent adhesion and splashing, and the pressure adjustment component realizes stepless adjustment and closed-loop control.

Benefits of technology

It improves soil breaking efficiency and uniformity, avoids damage to seedlings, ensures consistent compaction quality, increases seedling survival rate and work efficiency, and improves the working environment.

Abstract

The invention provides a forestry seedling cultivation soil covering and compacting device, and relates to the technical field of forestry seedling cultivation equipment, the forestry seedling cultivation soil covering and compacting device comprises a rack, and further comprises a hardened soil crushing assembly and an independent elastic pressing and covering assembly, the hardened soil crushing assembly comprises a support arm connected to the rack, walking wheels are installed on the support arm, one side of the rack is connected with a first support, and the first support is connected with a second support; according to the device, a crushing roller synchronously rotates along with advancing of the device, hardened soil on the surface of a seedbed is crushed, a uniform and loose soil condition is created for subsequent compaction, in an independent elastic pressing and covering assembly, a third hydraulic push rod adjusts the pitching angle of a second rotating frame, and the initial operation height of a fan-shaped soil pressing plate is set; the multiple independently-arranged swing arms drive the fan-shaped soil pressing plates to adapt to fluctuation of the ground correspondingly under the pre-compression effect of the pre-tightening springs, the crushed soil is evenly and elastically compacted, and the problem that uneven stress is prone to occurring in overall rigid compaction is fundamentally solved.
